Rezumat

The diversification of beech genotypes on the territory of the Republic of Moldova could be a so-lution to avoid the risks caused by climate change. The objective of this research was to determine the viability of beech seeds collected from four areas of the Ivano-Frankivsk region (Ukraine) and their modi-fication under the influence of various abiotic factors. The analyzed seeds possessed high viability (77.89 – 96.63%), which under the influence of supra optimal temperature +40°C decreased 1.3-1.4 times de-pending on the applied dose. Seeds exposed to heat treatment used reserve substances for radicle growth 1.4 – 1.6 times more than the control.
